TIE PLATE Fled June 18. 1929 M/vENToR Bumm/Inn f: aa'KnAN ATTO and uPatented June 24, 1936 TES lstie TIE PLATE Application filed .Tune 18,

This invention relates to tie-plates for railway rails, its object beingto provide a device of that character which shall be economical inmanufacture, convenient in its application to the rail and tier andwhich shall be rigid in its construction, firmly holding the rail inposition. Further objects are to make the plate adjustable as to variouswidths of the base flanges of the rails, and to provide extensivesurfaces of contact between the plate and the tie.

In the accompanying drawings I have shown that form of tie plate whichis now preferred; but the claims herein are not intended to be limitedto the exact structure shown any further-,than their express terms makenecessary. f

In the said drawings, Fig. 1 is a perspective view of my preferred formof tie-plate, the same vshowing the two members of the plate separatedor spaced apart in order more clearly to illustrate the specificstructure; Fig. 2 is a plan view of the said tie-plate on a reducedscale, with the parts assembled; Fig. 3 is a section through thetie-plate of F ig. 2, taken on the broken line 3 3 thereof, and showingthe manner in which the elements making up the plate are assembled withreference to the tiev and the railway rail.

That form of tie-plate which is shown in the drawing comprises twomembers, A and B, which are similar in shape to the letter L. Thesemembers are identical in structure and are interchangeable. Each memberat the angle of the L may be said to be of double thickness, asindicated in the portion marked 10. As will be seen from Fig. 3, thisthickened portion is adapted to rest directly upon the tie, which isindicated at 11. v`The thickened portion extends for substantially halfthe length of the member A or B, beyond which Vthe member is cut away onits lower side to form a relatively thin extension 12. Extendinglongitudinally of the rail from the thickened portion 10 is anotherthinned extension 13. As will be plain from Fig. 1, the thinned portions12 and 13 are at right angles to each other; and, whereas the portion 12projects from 1929. Serial 310.371,783.

the upper part of the thickened portion 10,

the thinned portion 13 projects vfrom the lower part of the thickenedportion. When the tie-plate is assembled, as shown in Figs. 2 and 3, thepart 12-of one member lies upon thc part 13 of the other member. Theseparts are each of substantially half the thickness of the part 10, sothat the assem bled plate is ofuniform thickness throughout, exceptthat, in applying it to rails having base flanges of different widths,`or to ties of greater or lesser widths, the members may be spaced apartmore or less, as indicated at 14 in Figs. 2 and 3.

Extending upwardly from the upper-.surfaces of the thickened portions 10of the members A and B are hooked projections 15, which are adapted toextend over the adjacent base flanges of the rail, which is indicated at16. In assembling, the mem bers A, and B are applied beneath the railfrom opposite sides of the latter until the hooked projections come intosubstantial contact with the base flanges of the rail.

The thinned portion 13 of each of theV members is provided with anelongated'slot 17, while the thickened portion 10 is provided with aspike hole 18 and the thin portion 12`with a similar spike hole 19. Whenthe tie-plate is assembled, the holes 19 register with the elongatedslots 17 so that spikes 2O may be inserted through the holes and slotsinto the tie 11, as shown in Fig. 3. Because of the elongated slots, themembers maybe spaced transversely of the rail more. or less and stillpermit the insertion of the spikes 20. In thisy way, therefore, the tieplate ismade adjustable for various widthsof base flanges of the rails.vFor holding down the thickened portions 10 ofV the members, spikes 21are passed through the holes 18 and forced into the tie.

The parts above described may be made out of any suitable material. Theportions which engage with the tie have extended areas in contact withthe latter so that the hammering incident to heavy traffic results incomparatively little damage to the ties. Ihe holes which are necessarilymade in the ties or spaced substantial distances from the rails and thematerial of the ties beneath the rails and adjacent the edges of 'thebase flanges of the latter remain intact and in condition for sustainingthe stresses due to heavy tratlic. Further, when the bolts or screws areset down tightly against the tieplate members, the parts which are incontact with the tie are drawn tightly against the latter, thus slightlyconipressing the libers of the tie and preventing moisture fromreachingtheholes in the tie.

Having thus described my invention what I claim as new is:

l. A tie-plate comprising a pair of niembers which are adapted to beassembled from opposite sides oi the rail, each of said ,memberscomprising a thickened portion adapted to rest upon the tie, a thinnerportion extending from the thickened portion in the direction oi" therail and also adapted to rest upon the tie, and a second thinner portionextending' from the thickened portion transversely of the rail andadapted to overlap the first mentioned thinner portion of' the oppositemember, the lirst mentioned thinnerr portion of each member beingprovided with an openingl therethrough and the second thinnerportionshaving openings therethrough adapted to register with the lirstmentioned openingsV for the reception of means for securing the membersto the tie.
